I have a subsequent report of findutils compiling OK on UNICOS on a Cray Y-MP.  
Hence I will assume that this problem has now been solved.

Summary:  configure problem with stdbool.h

Original Submission:  i'm in the process of checking out a snapshot provided to 
me by james youngman of a snapshot of the CVS tree of findutils, from 8 august.
i've had findutils-4.1 running on all the cray architectures for several years.
i'm having trouble getting the compile to complete for this snapshot.  the 
problem seems to be that there is no stdbool.h.
...
cc -DHAVE_CONFIG_H -I. -I. -I..     -g -c `test -f 'human.c' || echo 
'./'`human.c
CC-5 cc: ERROR File = human.h, Line = 30
  The source file "stdbool.h" is unavailable.

  # include <stdbool.h>
                       ^

make[5]: *** [human.o] Error 1
make[5]: Leaving directory `/ptmp/wendyp/finddir/findutils-4.2.0/gnulib/lib'

well, that's true, there is no stdbool.h on a non-X1 cray machine.

so, i checked out my redhat linux box, and it also does not have a stdbool.h 
file) but it completes compiling with no problem.

i don't understand this at all.  but i was able to overcome the confusion and 
find something that works.

"typedef char bool" works for gnulib/lib/human.h.
it looks like someone ran into a similar problem in find/defs.h, but the #ifdef 
structure there makes no sense to me. 

for the "bool" type to work on a UNICOS machine, the following patches are 
needed:

Looking in the "configure" file that we have in the CVS code,  it will generate 
a copy of stdbool.h if it thinks one is required.  I think this is also present 
in findutils-4.2.2 which you can download from 
ftp://alpha.gnu.org/gnu/findutils.   Could yo give that a try and let me know 
what you find out?
